You are right using available function is always better than accessing 
variables. (cause of later changes and maintainability..)

But however:
I just depends on what you want. This function traverses the rootline 
and returns the first found storage pid and siteroot.

It maybe not the expected result if I only want the storagepid from the 
curent site. (and maybe want to use $GLOBALS['TSFE']->id if no storage 
pid is set for the current site.)
